I see no-one here has been to Papua New Guinea.
All those above are child's-play compared to some of the runways there.
Here's one that's a little bit hard - Fane, in the highlands.
Something like a 12° slope, a small flat area on the top and a ~2,000' drop at the bottom.
Then there's Kamuli, which is similar but is bent in the middle. And yes, both these are RPT airports.
To land - you
have to land uphill and takeoff downhill - you fly level or climb a bit and then flare positively and go to takeoff power to make the top.
To takeoff, just add enough powre to start it rolling from the top.
And yes, there's worse around Asia as well.
